Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.

The heat dissipation device, the charging device, the electronic device, the charging system and the method thereof according to the embodiments of the present application are described below with reference to the accompanying drawings.

It should be noted that, the charging device provided by the embodiment of the application is used for charging the battery in the electronic device, and the heat dissipation device is used for dissipating heat of the electronic device. As one example, when the charging device charges the battery, for example, to perform high power charging, the heat dissipation device may help the electronic device dissipate heat during charging, achieving a temperature reduction effect. In the embodiment of the application, the heat dissipation device can be communicated with the charging equipment and also can be communicated with the electronic equipment. For example, the electronic device may communicate with the heat sink, acquire a status parameter of the heat sink when the electronic device recognizes that the heat sink is present, determine a current charging parameter according to the status parameter of the heat sink, and then send the current charging parameter to the charging device so that the charging device charges the battery according to the current charging parameter. For another example, the charging device may communicate with the heat sink, when the charging device recognizes that the heat sink is present, obtain a state parameter of the heat sink, and determine a current charging parameter (a required charging voltage, a required charging current, a required charging power, etc. of the charging device) according to the state parameter (temperature, etc.) of the heat sink, and then charge the battery according to the current charging parameter. In some examples, the electronic device may further send the state parameters of the heat sink assembly to the charging device after obtaining the state parameters of the heat sink assembly, so that the charging device determines the current charging parameters according to the state parameters of the heat sink assembly. Or, the charging device may further send the state parameter of the heat dissipation assembly to the electronic device after obtaining the state parameter of the heat dissipation assembly, so that the electronic device determines the current charging parameter according to the state parameter of the heat dissipation assembly.

Specifically, when the existence of the heat dissipation device is identified and the temperature of the heat dissipation itself is low, the required charging power of the charging equipment can be increased; when the existence of the heat sink is identified and the temperature of the heat sink itself is high, the charging power of the charging device can be reduced. It is understood that the adjustment of the charging power may be achieved by adjusting at least one of the charging voltage and the charging current.

Accordingly, the electronic device is cooled by the external cooling device, and high-power wired charging, for example, wired charging with power of 60W, 70W, 80W, 90W, 100W, or high-power wireless charging, for example, wireless charging with power of 20W, 25W, 30W, 35W, 40W, 45W, 50W, or the like, can be performed. In the prior art without a heat sink, the highest charging power of the wired charging can reach 50W, and the charging power higher than 50W is difficult to realize due to the problem of overhigh heat.

The following describes a heat dissipating device according to an embodiment of the present application in detail with reference to fig. 1 to 2.

Fig. 1 is a block schematic diagram of a heat dissipating device according to an embodiment of the present application. As shown in fig. 1, the heat dissipating device 100 includes a heat dissipating assembly 101 and a first communication control module 102.

The heat dissipation component 101 is configured to dissipate heat of the electronic device 300 being charged, that is, the heat dissipation component 101 dissipates heat of the electronic device 300 in a process that the charging device 200 charges the battery 310 in the electronic device 300. As one example, the heat dissipation assembly 101 may include at least one of a fan refrigeration assembly, a liquid water circulation refrigeration assembly, a liquid nitrogen refrigeration assembly, a semiconductor refrigeration assembly, and a compressor refrigeration assembly. That is, the heat dissipating device 100 has a cooling function, and the heat dissipating device 100 can dissipate heat from the electronic device 300 by any one of a fan cooling assembly, a liquid water circulation cooling assembly, a liquid nitrogen cooling assembly, a semiconductor cooling assembly, and a compressor cooling assembly, or can dissipate heat from the electronic device 300 by a combination of a plurality of cooling manners among the fan cooling assembly, the liquid water circulation cooling assembly, the liquid nitrogen cooling assembly, the semiconductor cooling assembly, and the compressor cooling assembly.

In particular, for fan cooling assemblies, the electronic device may be assisted in dissipating heat by controlling the rotation of the fan; for the liquid water circulation refrigeration component, the liquid water can be controlled to circulate and flow, and the heat exchange is carried out between the liquid water and the electronic equipment to help the electronic equipment to radiate heat; for the liquid nitrogen refrigerating component, the heat (refrigeration) of the periphery of the electronic equipment can be absorbed through the vaporization phenomenon of liquid nitrogen, so that the electronic equipment can be helped to radiate the heat; for the semiconductor refrigeration component, the cold face of the semiconductor refrigeration piece can be controlled to work so as to absorb the heat of the periphery of the electronic equipment, so that the electronic equipment can be helped to emit the heat; for a compressor refrigeration assembly, a compressor system (including a compressor, an evaporator, a condenser, etc.) can be controlled to perform refrigeration operation to absorb heat at the periphery of the electronic device, so as to help the electronic device dissipate the heat.

The first communication control module 102 is configured to communicate with at least one of the charging device 200 and the electronic device 300, where the first communication control module 102 is configured to feed back a status parameter of the heat dissipation component 101 during heat dissipation to the electronic device 300 and/or the charging device 200 that charges the electronic device 300, and the status parameter is configured to determine a charging current and/or a charging voltage of the charging device 200 that charges the electronic device 300, that is, a required charging current and/or a required charging voltage of the charging device 200 that charges the electronic device 300.

That is, the first communication control module 102 is configured to obtain a state parameter of the heat dissipation component during heat dissipation of the heat dissipation component 101, and send the state parameter of the heat dissipation component to at least one of the charging device 200 and the electronic device 300, so that at least one of the charging device 200 and the electronic device 300 determines a charging current and/or a charging voltage of the charging device 200 for charging the electronic device 300 according to the state parameter of the heat dissipation component.

Wherein the status parameter of the heat sink assembly comprises a parameter for indicating a current temperature of the heat sink or a parameter for indicating a current power consumption of the heat sink.

It is understood that the heat sink may have a function of communicating with the electronic device or may have a function of communicating with the charging device. For example, the first communication control module 102 may communicate with the electronic device 300 to send the state parameter of the heat dissipation assembly to the electronic device 300, at which time, the electronic device 300 determines the charging parameter according to the state parameter of the heat dissipation assembly. As another example, first communication control module 102 may communicate with charging device 200 to send a status parameter of the heat sink assembly to charging device 200, at which time charging device 200 determines a charging parameter based on the status parameter of the heat sink assembly.

Further, if the charging parameters are determined by the electronic device 300, the electronic device 300 may transmit the charging parameters to the charging device 200 so that the charging device 200 charges the battery according to the charging parameters. If the charging parameters are determined by the charging apparatus 200, the charging apparatus 200 may charge the battery directly according to the charging parameters.

Wherein the charging parameters of the charging device 200 for charging the electronic device 300 include at least one of a required charging voltage, a required charging current, and a required charging power. As one example, the required charging power is inversely related to the temperature of the heat sink and the required charging power is inversely related to the power consumption of the heat sink.

For example, when the charging device 200 charges the battery according to the charging parameters, the output voltage and/or the output current of the charging device 200 may be adjusted according to the current required charging voltage and/or the current required charging current, so that the output voltage and/or the output current of the charging device 200 matches the current required charging voltage and/or the current required charging current. It should be understood that "the output voltage and/or the output current of the charging device 200 matches the present required charging voltage and/or the present required charging current" includes: the output voltage and/or output current of charging device 200 is equal to or floats by a preset range (e.g., the voltage value floats up and down by 100 millivolts to 200 millivolts) from the current demand charging voltage and/or current demand charging current.

Therefore, the heat dissipation of the electronic equipment is realized through the external heat dissipation device, and higher power charging can be performed, so that the charging rate is improved to the greatest extent, the charging efficiency is improved, and the charging time is shortened.

Specifically, during actual use, the current charging parameter may be determined according to a preset parameter correspondence based on the current state parameter of the heat dissipating device. The parameter correspondence is used for indicating the correspondence between the state parameter and the charging parameter of the heat dissipation assembly.

It should be understood that the information of the above-described parameter correspondence relationship may be stored in the charging device or in the electronic device, depending on whether the determination subject of the charging parameter is the charging device 200 or the electronic device 300. For example, taking the current temperature of the heat sink as an example, the current temperature of the heat sink may be obtained by the charging apparatus 200, and the charging apparatus 200 may be used as a main body for determining the charging parameter, the charging apparatus 200 may determine the current charging parameter according to the information of the correspondence relationship between the current temperature of the heat sink and the parameter stored in the charging apparatus 200, wherein the charging apparatus 200 may directly obtain the current temperature of the heat sink by communicating with the heat sink 100, or the electronic apparatus 300 may obtain the current temperature of the heat sink by communicating with the heat sink 100, and the charging apparatus 200 receives the current temperature of the heat sink forwarded by the electronic apparatus 300.

Alternatively, the current temperature of the heat sink may be acquired by the electronic device 300, and the electronic device 300 may be a subject of determining the charging parameter, and the electronic device 300 may determine the current charging parameter according to the information of the correspondence relationship between the current temperature of the heat sink and the parameter stored in the electronic device 300, and then transmit the current charging parameter to the charging device 200. The electronic device 300 may directly obtain the current temperature of the heat dissipation device by communicating with the heat dissipation device 100, or the charging device 200 may obtain the current temperature of the heat dissipation device by communicating with the heat dissipation device 100, and the electronic device 300 receives the current temperature of the heat dissipation device forwarded by the charging device 200.

It should also be appreciated that the parameter correspondence may be determined by: and setting a plurality of temperature intervals, and measuring the optimal charging parameters corresponding to each temperature interval, such as maximum charging power, maximum charging current or maximum charging voltage. Then, the aforementioned parameter correspondence is constructed based on the optimal charging parameter corresponding to each temperature interval obtained by measurement.

For example, assuming that the parameter correspondence is used to indicate the correspondence between the temperature of the heat sink and the charging power, the current charging power may be determined according to the current temperature of the heat sink and through the parameter correspondence, and then the output power of the charging device 200 may be adjusted according to the current charging power so as to match the output power of the charging device 200 with the charging power.

Wherein "the output power of the charging device 200 matches the current charging power" includes: the output power of the charging device 200 is equal to the current charging power or floats by a preset range. Also, adjusting the output power of the charging device 200 may be achieved by adjusting the output voltage and/or the output current of the charging device 200.

It should be noted that, the implementation manner of determining the current charging parameter according to the current temperature of the heat dissipation device is basically consistent with the implementation manner of determining the current charging parameter according to the current temperature of the heat dissipation device, and will not be described in detail.

For wired charging, the output power of the charging device 200 may refer to the power of an electrical signal output by the wired charging device to the electronic device, and for wireless charging, the output power of the charging device 200 may refer to the power of an electromagnetic signal transmitted by the wireless charging device to the electronic device through the transmitting coil.

In some embodiments, the electronic device 300 may have a plurality of charging modes, such as a wired charging mode and a wireless charging mode, where different charging modes correspond to different parameter correspondence relationships, and at this time, a parameter correspondence relationship corresponding to the current charging mode may be selected from a plurality of pre-established parameter correspondence relationships based on the charging modes, where the plurality of parameter correspondence relationships respectively correspond to the plurality of charging modes, and each parameter correspondence relationship is used to indicate a mapping relationship between a state parameter of the heat dissipating device and a charging parameter in the charging mode corresponding to each parameter mapping relationship; and then determining the current charging parameters according to the current state parameters of the heat dissipation device and the corresponding parameter corresponding relation.

Therefore, the heat dissipation device dissipates heat of the electronic equipment in the process that the charging equipment charges the battery in the electronic equipment, so that the heat dissipation of the electronic equipment is realized through the external heat dissipation device, the heat dissipation device communicates with at least one of the charging equipment and the electronic equipment, and the state parameters of the heat dissipation components are interacted, so that the current charging parameters of the charging process are adjusted, and therefore, higher-power charging can be performed, the charging rate is improved to the greatest extent, the charging efficiency is improved, and the charging time is shortened.

In embodiments of the present application, an electronic device may refer to a mobile terminal, which may include, but is not limited to, a smart phone, a computer, a personal digital assistant (personal digital assistant, PDA), a wearable device, a bluetooth headset, a gaming device, a camera device, etc. The charging device may be a device having a function of charging the terminal, such as an adapter, a mobile power supply (charger) or an in-vehicle charger.

In some embodiments of the present application, the first communication control module 102 is configured to communicate with the electronic device 300 and/or the charging device 200 to determine whether to turn on the heat sink assembly 101. It should be appreciated that heat sink assembly 101 may be turned on based on communication with electronic device 300, or may be turned on based on communication with charging device 200, thereby enabling automatic turning on of heat sink 100.

As one example, the first communication control module 102 is configured to determine to turn on the heat dissipation component 101 when receiving detection information sent by the electronic device 300 and/or the charging device 200.

For example, the detection information may be information that informs the heat sink to send the state parameters of the heat dissipating component to the electronic device 300 during heat dissipation. Specifically, when the electronic device 300 enters a mode that the state parameters of the heat dissipation assembly control charging, the electronic device 300 may send detection information to the heat dissipation device 100, when the heat dissipation device 100 receives the detection information, it is determined to turn on the heat dissipation assembly 101, and then the state parameters of the heat dissipation assembly in the heat dissipation process are fed back to the electronic device 300, so that the electronic device 300 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information. Alternatively, the detection information may be information informing the heat sink to transmit the state parameter of the heat sink during heat dissipation to the charging apparatus 200. Specifically, when the charging device 200 enters a mode of controlling charging by using the state parameter of the heat dissipation component, the charging device 200 may send detection information to the heat dissipation device 100, when the heat dissipation device 100 receives the detection information, it is determined to turn on the heat dissipation component 101, and then the state parameter of the heat dissipation component in the heat dissipation process is fed back to the charging device 200, and the charging device 200 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

As another example, the detection information may be information that the electronic device 300 recognizes the heat sink 100. Specifically, after the electronic device 300 recognizes the heat dissipating device 100, the electronic device 300 may send detection information to the heat dissipating device 100, when the heat dissipating device 100 receives the detection information, determine to turn on the heat dissipating component 101, and then feed back the state parameter of the heat dissipating component in the heat dissipating process to the electronic device 300, and the electronic device 300 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information. Alternatively, the detection information may be information indicating that the heat sink 100 is recognized by the charging apparatus 200. Specifically, after the charging device 200 recognizes the heat dissipating device 100, detection information may be sent to the heat dissipating device 100, when the heat dissipating device 100 receives the detection information, it is determined to turn on the heat dissipating component 101, and then state parameters of the heat dissipating component in the heat dissipating process are fed back to the charging device 200, and the charging device 200 may determine a charging current and/or a charging voltage of the charging device for charging the electronic device according to the state information.

It should be noted that, when receiving the detection information sent by the electronic device 300 and/or the charging device 200, the first communication control module 102 may also send feedback information to the electronic device 300 and/or the charging device 200, where the feedback information is used to inform that the electronic device 300 and/or the charging device 200 will turn on the heat dissipation assembly 101.

As another example, the first communication control module 102 is configured to determine to turn on the heat dissipation assembly 101 when it is determined that the charging mode of the electronic device 300 and/or the charging device 200 is a preset charging mode. It should be noted that the preset charging mode may be a high-power charging mode, for example, in the high-power charging mode, the charging power of the electronic device 300 may be more than 50W. The charging power of 50W or more requires the heat dissipation assembly 101 to dissipate heat from the electronic device being charged.

It should be understood that, after the electronic device 300 identifies the heat dissipating device 100, the electronic device may send information including a charging mode to the heat dissipating device 100, and after the heat dissipating device 100 receives the information including the charging mode, determine whether the charging mode is a preset charging mode, and if the charging mode is the preset charging mode, determine to turn on the heat dissipating component 101. Then, the heat dissipating device 100 may feed back the state parameter of the heat dissipating component 101 during the heat dissipating process to the electronic device 300, and the electronic device 300 may determine the charging current and/or the charging voltage for the charging device to charge the electronic device according to the state information. Alternatively, after identifying the heat sink 100, the charging apparatus 200 may send information including a charging mode to the heat sink 100, and after receiving the information including the charging mode, the heat sink 100 determines whether the charging mode is a preset charging mode, and if the charging mode is the preset charging mode, determines to turn on the heat sink 101. Then, the heat dissipating device 100 may feed back the state parameter of the heat dissipating component 101 during the heat dissipating process to the charging device 200, and the charging device 200 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

It should be further noted that, when determining that the charging mode of the electronic device 300 and/or the charging device 200 is the preset charging mode, the first communication control module 102 may further send feedback information to the electronic device 300 and/or the charging device 200, where the feedback information is used to inform that the electronic device 300 and/or the charging device 200 will turn on the heat dissipation assembly 101.

In some examples, the first communication control module 102 is further configured to turn off the heat dissipation assembly 101 when it is determined that the charging mode of the electronic device 300 and/or the charging device 200 is switched from the preset charging mode to the other charging mode during the charging of the electronic device by the charging device. Thus, during charging, if the charging mode is switched, the heat sink is turned off.

According to one embodiment of the present application, the first communication control module 102 is configured to send identification information to at least one of the charging device 200 and the electronic device 300, where the identification information is configured to inform that the charging device 200 or the electronic device 300 may perform charging in a preset charging mode. That is, the heat sink 100 actively initiates the identification, for example, the heat sink 100 may send identification information to the charging device 200 after detecting the connection with the charging device 200 to inform the charging device 200 that the charging device 200 may be charged in the preset charging mode, and the heat sink 100 may send identification information to the electronic device 300 after detecting the connection with the electronic device 300 to inform the electronic device 300 that the charging device 300 may be charged in the preset charging mode. For another example, a pressure sensor may be disposed on the heat dissipating device 100, and when the pressure sensor senses that the charging device 200 or the electronic device 300 is placed, identification information may be sent to the charging device 200 or the electronic device 300 to inform that the charging device 200 or the electronic device 300 may be charged in a preset charging mode. That is, the first communication control module 102 may also transmit the identification information of the heat sink to at least one of the charging apparatus 200 and the electronic apparatus 300 before the charging apparatus charges the electronic apparatus, so that the at least one of the charging apparatus 200 and the electronic apparatus 300 identifies the heat sink 100 according to the identification information of the heat sink.

Specifically, after the first communication control module 102 establishes communication with the charging device 200, the first communication control module 102 may first obtain the identification information of the heat dissipating device and send the identification information of the heat dissipating device to the charging device 200, after the charging device 200 receives the identification information of the heat dissipating device, it may determine whether the identification information of the heat dissipating device is matched with, for example, the identification information pre-stored in the charging device 200, and if so, it indicates that the heat dissipating device matched with the charging device 200 is identified, at this time, the charging device 200 determines that the identification is successful, and may perform charging in a high-power charging mode with relatively high heat generation, that is, obtain the current state parameter of the heat dissipating device, and adjust the charging parameter according to the state parameter of the heat dissipating component in the charging process.

Similarly, after the first communication control module 102 establishes communication with the electronic device 300, the first communication control module 102 may first obtain the identification information of the heat dissipating device and send the identification information of the heat dissipating device to the electronic device 300, after the electronic device 300 receives the identification information of the heat dissipating device, it may be determined whether the identification information of the heat dissipating device is matched with, for example, the identification information pre-stored in the electronic device 300, if so, it is determined that the heat dissipating device matched with the electronic device 300 is identified, at this time, the electronic device 300 determines that the identification is successful, and may use a high-power charging mode with relatively large heat generation to perform charging, that is, obtain the current state parameter of the heat dissipating device, and adjust the charging parameter according to the state parameter of the heat dissipating component in the charging process.

Therefore, the heat dissipation device matched with the charging equipment and the electronic equipment can be used for dissipating heat, and the safety and the high efficiency of the charging process are ensured.

According to some embodiments of the present application, the first communication control module 202 is further configured to obtain temperature information of the electronic device 300 during the charging process, and adjust the heat dissipation strength or the heat dissipation power of the heat dissipation component 101 according to the temperature information.

Specifically, in actual use, the first communication control module 202 may determine the heat dissipation strength or the heat dissipation power of the heat dissipation component 101 according to a preset parameter correspondence based on the temperature of the battery of the electronic device 300 during the charging process. The parameter correspondence is used to indicate the correspondence between the temperature of the battery and the heat dissipation intensity or heat dissipation power of the heat dissipation assembly 101.

That is, in terms of charging, the charging device 200 may be a wired charging unit, the wired charging device may charge a battery in the electronic device 300 in a wired manner, for example, the wired charging device (such as an adapter or the like) may be directly connected to a charging interface of the electronic device, the wired charging device charges the battery in the electronic device through a power line in the charging interface, and, for example, the wired charging device may be connected to the charging interface of the electronic device through a heat sink, the wired charging device charges the battery in the electronic device through a charging circuit in the heat sink, and through the power line in the charging interface. Alternatively, the charging device 200 may be a wireless charging device, where the wireless charging device may convert an ac power coupleable to a transmitting coil into an electromagnetic signal through the transmitting coil to transmit, and the electronic device 300 may convert the electromagnetic signal transmitted by the transmitting coil of the wireless charging device into an ac power through the receiving coil, and perform operations such as rectifying and/or filtering the ac power, and convert the ac power into a stable dc power to charge the battery.

In terms of communication, the first communication control module 102 may employ a wired communication unit capable of communicating with at least one of the charging device 200 and the electronic device 300 in a wired communication manner, for example, the heat sink 100 and the charging device 200 may be connected in a wired manner to perform wired communication, and the heat sink 100 may also be connected in a wired manner to the electronic device 300 to perform wired communication. The first communication control module 102 may employ a Wireless communication unit capable of communicating with at least one of the charging device 200 and the electronic device 300 in a Wireless communication manner, for example, the Wireless communication unit may communicate with at least one of the charging device 200 and the electronic device 300 in a communication manner such as Wi-Fi (Wireless-Fidelity), bluetooth, NFC (Near Field Communication, short-range Wireless communication technology), or the like.

It should be noted that, when the charging device 200 performs wired charging on the battery, the first communication control module 102 may adopt a wired communication mode or a wireless communication mode according to actual situations, and may be capable of implementing communication, for example, when the wired charging device is directly connected to the charging interface of the electronic device, the first communication control module 102 may adopt the wireless communication mode to communicate with at least one of the charging device 200 and the electronic device 300; as another example, when the wired charging device may be connected to the charging interface of the electronic device through the heat dissipating device, the first communication control module 102 may communicate with at least one of the charging device 200 and the electronic device 300 in a wired communication manner. Similarly, when the charging device 200 charges the battery wirelessly, the first communication control module 102 may use a wired communication method or a wireless communication method according to actual situations, and as a preferred example, the first communication control module 102 may use a wireless communication method to communicate with at least one of the charging device 200 and the electronic device 300.

According to an embodiment of the present application, as shown in fig. 2, the heat dissipating device 100 further includes a first connection interface B1 and a second connection interface B2, where the first connection interface B1 is used for connecting with a wired charging device, and the second connection interface B2 is used for connecting with the electronic device 300. Thereby, the charging device 200, the heat sink 100, and the electronic device 300 are connected in series, and thus, through this series path, wired communication can be realized while wired charging is realized.

Specifically, the wired communication unit performs wired communication with the charging device 200 through the data line in the first connection interface B1; and/or the wired communication unit performs wired communication with the electronic device 300 through the data line in the second connection interface B2.

After the wired charging device is connected to the heat dissipating device 100 through the first connection interface B1 and the electronic device 300 is connected to the heat dissipating device 100 through the second connection interface B2, the wired charging device charges the battery in the electronic device 300 through the power line in the first connection interface B1 and the power line in the second connection interface B2.

It may be appreciated that the first connection interface B1 has a power line and a data line, the second connection interface B2 also has a power line and a data line, the power line in the first connection interface B1 may be connected to the power line in the second connection interface B2 through a charging circuit, and the charging circuit may be a wire, so that the charging device 200 may be connected to the power line in the charging interface of the electronic device 300 through the power line in the first connection interface B1, the charging circuit, and the power line in the second connection interface B2, and charge the battery through the power line in the charging interface. Further, the heat sink 100 may perform wired communication with the charging device 200 through a data line in the first connection interface B1, and may also perform wired communication with the electronic device 300 through a data line in the second connection interface B2. Thus, by connecting the charging device 200, the heat sink 100, and the electronic device 300 in series, wired charging and wired communication can be simultaneously achieved in the same series path.

According to one embodiment of the application, the wireless charging device is provided integrally with the heat sink. That is, the heat dissipation device may have a wireless charging function, and the heat dissipation device may construct a wireless charging device through a circuit such as a transmitting coil, so that the electronic device 300 is charged through the wireless charging device, and meanwhile, the heat dissipation device may also dissipate heat generated by the wireless charging device in a wireless charging process, thereby improving the wireless charging power.

In addition, according to some embodiments of the application, the heat sink may be connected to an external power source to supply power to the heat sink via the external power source. Or, a power module can be further arranged in the heat dissipation device, and the power module can convert the voltage on the power line in the first connection interface B1 or the second connection interface B2 into a power supply required by the heat dissipation device so as to supply power to the heat dissipation device. Alternatively, a battery may be disposed in the heat sink, and the heat sink may be powered by the battery.

Next, a charging device according to an embodiment of the present application will be described in detail with reference to fig. 3.

Fig. 3 is a block schematic diagram of a charging device according to an embodiment of the present application. As shown in fig. 3, the charging apparatus 200 includes a first charging module 201 and a second communication control module 202.

The second communication control module 202 is configured to communicate with the heat dissipation device 100 to obtain a state parameter of a heat dissipation component in the heat dissipation device 100 during a heat dissipation process, determine a charging current and/or a charging voltage of the charging device 200 for charging the electronic device 300 according to the state parameter, and control the first charging module 201 to charge a battery in the electronic device 300 according to the charging current and/or the charging voltage, where the heat dissipation component is configured to dissipate heat of the charging electronic device 300.

That is, the second communication control module 202 obtains the state parameter of the heat sink 100 by communicating with the heat sink, and the second communication control module 202 determines the current charging parameter of the charging process according to the state parameter of the heat sink, and charges the battery in the electronic device through the first charging module 201 according to the current charging parameter, wherein the state parameter of the heat sink includes a parameter for indicating the current temperature of the heat sink or a parameter for indicating the current power consumption of the heat sink.

It is understood that the charging apparatus 200 may or may not have a function of communicating with the heat sink 100. When the charging device 200 has the function of communicating with the heat dissipating device 100, the second communication control module 202 may directly communicate with the heat dissipating device 100 to obtain the status parameter of the heat dissipating component. When the charging device 200 does not have the function of communicating with the heat dissipating device 100, the electronic device 300 may communicate with the heat dissipating device 100 to enable the electronic device 300 to obtain the state parameter of the heat dissipating component, and then the second communication control module 202 communicates with the electronic device 300 to obtain the state parameter of the heat dissipating component. Further, after the charging device 200 obtains the state parameter of the heat dissipation assembly, the current charging parameter may be determined according to the state parameter of the heat dissipation assembly, and the battery may be directly charged according to the current charging parameter.

According to an embodiment of the present application, the second communication control module 202 determines the current charging parameter, such as the charging current and/or the charging voltage, that is, the required charging current and/or the required charging voltage, according to the current state parameter of the heat dissipating device through a pre-established parameter correspondence, where the parameter correspondence is used to indicate the correspondence between the state parameter of the heat dissipating device and the charging parameter, and the charging parameter includes at least one of the required charging voltage, the required charging current, and the required charging power of the charging device.

For example, the second communication control module 202 may adjust the output voltage and/or the output current of the charging device 200 according to the current required charging voltage and/or the current required charging current when charging the battery according to the current charging parameters, such that the output voltage and/or the output current of the charging device 200 matches the current required charging voltage and/or the current required charging current. It should be understood that "the output voltage and/or the output current of the charging device 200 matches the present required charging voltage and/or the present required charging current" includes: the output voltage and/or output current of charging device 200 is equal to or floats by a preset range (e.g., the voltage value floats up and down by 100 millivolts to 200 millivolts) from the current demand charging voltage and/or current demand charging current.

Specifically, during actual use, the second communication control module 202 may determine the current charging parameter according to a preset parameter correspondence based on the current state parameter of the heat dissipating device. The parameter correspondence is used for indicating the correspondence between the state parameter and the charging parameter of the heat dissipation assembly.

It should be appreciated that the parameter correspondence may be determined by: a plurality of temperature intervals may be set, and an optimal charging parameter, such as a maximum charging power, a maximum charging current, or a maximum charging voltage, corresponding to each temperature interval is measured. Then, the aforementioned parameter correspondence is constructed based on the optimal charging parameter corresponding to each temperature interval obtained by measurement. Alternatively, a plurality of power consumption intervals may be set, and an optimal charging parameter, such as a maximum charging power, a maximum charging current, or a maximum charging voltage, corresponding to each power consumption interval is measured. Then, the aforementioned parameter correspondence is constructed based on the optimal charging parameter corresponding to each power consumption interval obtained by measurement.

For example, assuming that the parameter correspondence is used to indicate the correspondence between the temperature of the heat dissipation device and the required charging power, the second communication control module 202 may determine the current required charging power according to the current temperature of the heat dissipation device and through the parameter correspondence, and then may adjust the output power of the charging device 200 according to the current required charging power so as to match the output power of the charging device 200 with the current required charging power.

Wherein "the output power of the charging device 200 matches the current required charging power" includes: the output power of the charging device 200 is equal to the current required charging power or floats by a preset range. Also, adjusting the output power of the charging device 200 may be achieved by adjusting the output voltage and/or the output current of the charging device 200.

In some embodiments, the electronic device 300 may have a plurality of charging modes, such as a wired charging mode and a wireless charging mode, where different charging modes correspond to different parameter correspondence relationships, and at this time, the second communication control module 202 may first select, from a plurality of pre-established parameter correspondence relationships, a parameter correspondence relationship corresponding to a current charging mode based on the charging modes, where the plurality of parameter correspondence relationships respectively correspond to the plurality of charging modes, and each parameter correspondence relationship is used to indicate a mapping relationship between a state parameter of the heat dissipation component and a charging parameter in the charging mode corresponding to each parameter mapping relationship; and then determining the current charging parameters according to the current state parameters of the heat dissipation device and the corresponding parameter corresponding relation.

Therefore, the heat dissipation device dissipates heat of the electronic equipment in the process that the charging equipment charges the battery in the electronic equipment, so that the heat dissipation of the electronic equipment is realized through the external heat dissipation device, the charging equipment communicates through the heat dissipation device or the electronic equipment, and the state parameters of the heat dissipation components are interacted, so that the current charging parameters of the charging process are adjusted, and therefore, higher-power charging can be carried out, the charging rate is improved to the greatest extent, the charging efficiency is improved, and the charging time is shortened.

According to one embodiment of the present application, the required charging power is inversely related to the temperature of the heat sink. That is, when the temperature of the heat dissipating device itself is low, the wired charging power or the wireless charging power of the charging device is increased; when the temperature of the heat dissipation device is higher, the wired charging power or the wireless charging power of the charging equipment is reduced. And, the required charging power and the consumption power of the heat dissipating device are in negative correlation, that is, when the temperature of the heat dissipating device is small, the wired charging power or the wireless charging power of the charging device is improved; when the heat dissipation device consumes larger power, the wired charging power or the wireless charging power of the charging equipment is reduced.

In some embodiments of the present application, the second communication control module 202 communicates with the heat sink 100 to determine whether to turn on the heat sink assembly by the heat sink 100. It should be appreciated that heat sink assembly 101 may be turned on based on communication with electronic device 300, or may be turned on based on communication with charging device 200, thereby enabling automatic turning on of heat sink 100.

As an example, the second communication control module 202 is configured to send detection information to the heat dissipating device 100, where the detection information is used to instruct the heat dissipating device 100 to turn on the heat dissipating component.

For example, the detection information may be information informing the heat sink to transmit a state parameter of the heat sink during heat dissipation to the charging apparatus 200. Specifically, when the charging device 200 enters a mode of controlling charging by using the state parameter of the heat dissipation component, the charging device 200 may send detection information to the heat dissipation device 100, when the heat dissipation device 100 receives the detection information, it is determined to turn on the heat dissipation component 101, and then the state parameter of the heat dissipation component in the heat dissipation process is fed back to the charging device 200, and the charging device 200 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

As another example, the detection information may be information that the charging apparatus 200 recognizes the heat sink 100. Specifically, after the charging device 200 recognizes the heat dissipating device 100, detection information may be sent to the heat dissipating device 100, when the heat dissipating device 100 receives the detection information, it is determined to turn on the heat dissipating component 101, and then state parameters of the heat dissipating component in the heat dissipating process are fed back to the charging device 200, and the charging device 200 may determine a charging current and/or a charging voltage of the charging device for charging the electronic device according to the state information.

As another example, the second communication control module 202 is configured to send the charging mode of the electronic device 300 to the heat sink 100, so that the heat sink 100 determines to turn on the heat sink assembly when the charging mode of the electronic device 300 is a preset charging mode. It should be noted that the preset charging mode may be a high-power charging mode, for example, in the high-power charging mode, the charging power of the electronic device 300 may be more than 50W. The charging power of 50W or more requires a heat dissipation assembly to dissipate heat of the electronic device being charged.

It should be understood that, after identifying the heat dissipating device 100, the charging apparatus 200 may send information including a charging mode to the heat dissipating device 100, and after receiving the information including the charging mode, the heat dissipating device 100 determines whether the charging mode is a preset charging mode, and if the charging mode is the preset charging mode, determines to turn on the heat dissipating component 101. Then, the heat dissipating device 100 may feed back the state parameter of the heat dissipating component 101 during the heat dissipating process to the charging device 200, and the charging device 200 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

In some examples, during charging of electronic device 300 by charging device 200, charging device 200 may also send information including a charging module to heat sink 100, and heat sink 100 may turn off heat sink 101 when it is determined that the charging mode is switched from the preset charging mode to the other charging mode. Thus, during charging, if the charging mode is switched, the heat sink is turned off.

According to an embodiment of the present application, the second communication control module 202 determines that the charging device 200 can be charged in a preset charging mode after receiving the identification information transmitted from the heat sink 100. That is, the heat sink 100 actively initiates the identification, for example, the heat sink 100 may transmit identification information to the charging apparatus 200 after detecting the connection with the charging apparatus 200 to inform the charging apparatus 200 that the charging may be performed in the preset charging mode. For another example, a pressure sensor may be disposed on the heat dissipating device 100, and when the pressure sensor senses that the charging device 200 is placed, identification information may be sent to the charging device 200 to inform the charging device 200 that the charging device may perform charging in a preset charging mode.

That is, the charging apparatus 200 may acquire the temperature of the heat sink after recognizing the presence of the heat sink, and adjust the charging parameter according to the current temperature of the heat sink. As one example, the charging apparatus 200 may identify the heat sink 100 by communicating with the heat sink 100, in other words, the second communication control module 202 may confirm that the heat sink 100 is identified as being present after receiving the identification information transmitted by the heat sink 100.

Specifically, the second communication control module 202 is further configured to, before the charging device charges the electronic device, communicate with the heat dissipating device 100 to obtain the identification information of the heat dissipating device, and identify the heat dissipating device 100 according to the identification information of the heat dissipating device, so as to determine the current charging parameter of the charging process according to the state parameter of the heat dissipating component after the identification is successful.

That is, after the second communication control module 202 establishes communication with the heat sink 100, the second communication control module 202 may first receive the identification information of the heat sink, determine whether the identification information of the heat sink matches, for example, the identification information pre-stored in the charging device 200, and if so, indicate that the charging device 200 matches with the identified heat sink 100, at this time, the charging device 200 determines that the identification is successful, and may use a high-power charging mode with relatively high heat generation to perform charging, that is, obtain the current state parameter of the heat sink, and adjust the charging parameter according to the state parameter of the heat sink during charging.

Therefore, the heat dissipation device matched with the charging equipment can be used for dissipating heat, and the safety and the high efficiency of the charging process can be ensured.

An electronic device according to an embodiment of the present application is described in detail below with reference to fig. 4.

Fig. 4 is a block schematic diagram of an electronic device according to an embodiment of the application. As shown in fig. 4, the electronic device 300 includes a second charging module 301 and a third communication control module 302.

The third communication control module 302 is configured to communicate with the heat dissipation device 100 to obtain a state parameter of a heat dissipation component in the heat dissipation device 100 during a heat dissipation process, and determine a charging parameter, such as a charging current and/or a charging voltage, of the charging device 200 for charging the electronic device 300 according to the state parameter, that is, a required charging current and/or a required charging voltage, and communicate with the charging device 200 to send the charging current and/or the charging voltage to the charging device 200, so that the charging device 200 charges a battery in the electronic device 300 through the second charging module 301 according to the charging current and/or the charging voltage, where the heat dissipation component is configured to dissipate heat of the charging electronic device 300.

That is, the third communication control module 302 obtains a state parameter of the heat sink assembly by communicating with the heat sink 100 or the charging apparatus 200, the state parameter of the heat sink assembly includes a parameter indicating a current temperature of the heat sink or a parameter indicating a current consumption power of the heat sink, and the charging parameter includes at least one of a required charging voltage, a required charging current, and a required charging power of the charging apparatus by communicating with the charging apparatus 200 to transmit the current charging parameter to the charging apparatus 200 so that the charging apparatus 200 charges a battery in the electronic apparatus 300 through the second charging module 301 according to the received current charging parameter, wherein the heat sink 100 is used for dissipating heat of the electronic apparatus 300 during the charging of the battery in the electronic apparatus 300 by the charging apparatus 200.

It is understood that the electronic device 300 may or may not have the function of communicating with the heat sink 100. When the electronic device 300 has the function of the heat dissipating device 100 for communication, the third communication control module 302 may directly communicate with the heat dissipating device 100 to obtain the status parameters of the heat dissipating component. When the electronic device 300 does not have the function of communicating with the heat dissipating device 100, the communication may be performed with the heat dissipating device 100 through the charging device 200, so that the charging device 200 obtains the state parameter of the heat dissipating component, and then the third communication control module 302 obtains the state parameter of the heat dissipating component through the communication with the charging device 200. Further, after the electronic device 300 obtains the state parameter of the heat dissipation component, the current charging parameter may be determined according to the state parameter of the heat dissipation component, and the current charging parameter may be sent to the charging device 200, so that the charging device 200 charges the battery according to the current charging parameter.

According to an embodiment of the present application, the third communication control module 302 determines the current charging parameter according to the current state parameter of the heat dissipation assembly through a pre-established parameter correspondence, where the parameter correspondence is used to indicate a correspondence between the state parameter of the heat dissipation assembly and the charging current and/or the charging voltage.

For example, when charging device 200 charges a battery according to the current charging parameters, charging device 200 may adjust the output voltage and/or output current of charging device 200 according to the current demand charging voltage and/or current demand charging current such that the output voltage and/or output current of charging device 200 matches the current demand charging voltage and/or current demand charging current. It should be understood that "the output voltage and/or the output current of the charging device 200 matches the present required charging voltage and/or the present required charging current" includes: the output voltage and/or output current of charging device 200 is equal to or floats by a preset range (e.g., the voltage value floats up and down by 100 millivolts to 200 millivolts) from the current demand charging voltage and/or current demand charging current.

Specifically, in actual use, the third communication control module 302 may determine the current charging parameter according to the preset parameter correspondence based on the current state parameter of the heat dissipating device, and send the current charging parameter to the charging device 200. The parameter correspondence is used for indicating the correspondence between the state parameter and the charging parameter of the heat dissipation assembly.

For example, assuming that the parameter correspondence is used to indicate the correspondence between the temperature of the heat dissipation device and the required charging power, the third communication control module 302 may determine the required charging power according to the current temperature of the heat dissipation device and send the required charging power to the charging device 200 according to the parameter correspondence, and then the charging device 200 may adjust the output power of the charging device 200 according to the required charging power so as to match the output power of the charging device 200 with the required charging power.

In some embodiments, the electronic device 300 may have a plurality of charging modes, such as a wired charging mode and a wireless charging mode, where different charging modes correspond to different parameter correspondence relationships, and in this case, the third communication control module 302 may first select, from a plurality of pre-established parameter correspondence relationships, a parameter correspondence relationship corresponding to a current charging mode based on the electrical charging mode, where the plurality of parameter correspondence relationships respectively correspond to the plurality of charging modes, and each parameter correspondence relationship is used to indicate a mapping relationship between a state parameter of the heat dissipation assembly and a charging parameter in the charging mode corresponding to each parameter mapping relationship; and then determining the current charging parameters according to the current state parameters of the heat dissipation device and the corresponding parameter corresponding relation.

Therefore, the heat dissipation device dissipates heat of the electronic equipment in the process that the charging equipment charges the battery in the electronic equipment, so that the heat dissipation of the electronic equipment is realized through the external heat dissipation device, the electronic equipment communicates through the heat dissipation device or the charging equipment, and the state parameters of the heat dissipation components are interacted, so that the current charging parameters of the charging process are adjusted, and therefore, higher-power charging can be carried out, the charging rate is improved to the greatest extent, the charging efficiency is improved, and the charging time is shortened.

In some embodiments of the present application, the third communication control module 302 communicates with the heat sink 100 to determine whether to turn on the heat sink assembly by the heat sink 100. It should be appreciated that heat sink assembly 101 may be turned on based on communication with electronic device 300, or may be turned on based on communication with charging device 200, thereby enabling automatic turning on of heat sink 100.

As one example, the third communication control module 302 is configured to send detection information to the heat sink 100, where the detection information is configured to instruct the heat sink to turn on the heat sink assembly.

For example, the detection information may be information that informs the heat sink to send the state parameters of the heat dissipating component to the electronic device 300 during heat dissipation. Specifically, when the electronic device 300 enters a mode that the state parameters of the heat dissipation assembly control charging, the electronic device 300 may send detection information to the heat dissipation device 100, when the heat dissipation device 100 receives the detection information, it is determined to turn on the heat dissipation assembly 101, and then the state parameters of the heat dissipation assembly in the heat dissipation process are fed back to the electronic device 300, so that the electronic device 300 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

As another example, the detection information may be information that the electronic device 300 recognizes the heat sink 100. Specifically, after the electronic device 300 recognizes the heat dissipating device 100, the electronic device 300 may send detection information to the heat dissipating device 100, when the heat dissipating device 100 receives the detection information, determine to turn on the heat dissipating component 101, and then feed back the state parameter of the heat dissipating component in the heat dissipating process to the electronic device 300, and the electronic device 300 may determine the charging current and/or the charging voltage of the charging device for charging the electronic device according to the state information.

As another example, the third communication control module 302 is configured to send the charging mode of the electronic device 300 to the heat dissipation device 100, so that the heat dissipation device 100 determines to turn on the heat dissipation component when the charging mode of the electronic device 300 is the preset charging mode. It should be noted that the preset charging mode may be a high-power charging mode, for example, in the high-power charging mode, the charging power of the electronic device 300 may be more than 50W. The charging power of 50W or more requires the heat dissipation assembly 101 to dissipate heat from the electronic device being charged.

It should be understood that, after the electronic device 300 identifies the heat dissipating device 100, the electronic device may send information including a charging mode to the heat dissipating device 100, and after the heat dissipating device 100 receives the information including the charging mode, determine whether the charging mode is a preset charging mode, and if the charging mode is the preset charging mode, determine to turn on the heat dissipating component 101. Then, the heat dissipating device 100 may feed back the state parameter of the heat dissipating component 101 during the heat dissipating process to the electronic device 300, and the electronic device 300 may determine the charging current and/or the charging voltage for the charging device to charge the electronic device according to the state information.

In some examples, during charging of the electronic device by the charging device, the electronic device 300 may send information including a charging mode to the heat sink 100, and the heat sink 100 turns off the heat sink 101 when it is determined that the charging mode of the electronic device 300 is switched from a preset charging mode to another charging mode. Thus, during charging, if the charging mode is switched, the heat sink is turned off.

According to an embodiment of the present application, the third communication control module 302 determines that the electronic device 300 can be charged in the preset charging mode after receiving the identification information sent by the heat sink 100. That is, the heat sink 100 actively initiates the identification, for example, after the heat sink 100 detects that it is connected to the electronic device 300, the heat sink 100 may send identification information to the electronic device 300 to inform the electronic device 300 that it may be charged in a preset charging mode. For another example, a pressure sensor may be disposed on the heat dissipating device 100, and when the pressure sensor senses that the electronic device 300 is placed, identification information may be sent to the electronic device 300 to inform the electronic device 300 that the electronic device 300 may be charged in a preset charging mode.

In addition, according to one embodiment of the present application, the electronic device 300 may acquire the temperature of the heat sink after recognizing the presence of the heat sink, and adjust the charging parameter according to the current temperature of the heat sink. As one example, the electronic device 300 may identify the heat sink 100 by communicating with the heat sink 100, in other words, the third communication control module 302 may confirm that the heat sink 100 is identified as being present after receiving the identification information transmitted by the heat sink 100.

Specifically, the third communication control module 302 is further configured to, before the charging device charges the electronic device, communicate with the heat dissipating device 100 or the charging device 200 to obtain the identification information of the heat dissipating device, and identify the heat dissipating device 100 according to the identification information of the heat dissipating device, so as to determine the current charging parameter of the charging process according to the state parameter of the heat dissipating component after the identification is successful.

That is, after the third communication control module 302 establishes communication with the heat sink 100 or the charging device 200, the third communication control module 302 may first receive the identification information of the heat sink, determine whether the identification information of the heat sink is matched with the identification information pre-stored in the electronic device 300, for example, and if so, indicate that the heat sink matched with the electronic device 300 is identified, at this time, the electronic device 300 determines that the identification is successful, and may use a high-power charging mode with relatively high heat generation to perform charging, that is, obtain the current state parameter of the heat sink, and adjust the charging parameter according to the state parameter of the heat sink during the charging process.

Therefore, the heat dissipation device matched with the electronic equipment can be used for dissipating heat, and the safety and the high efficiency of the charging process can be ensured.

According to some embodiments of the present application, the third communication control module 302 is further configured to feed back temperature information of the electronic device 300 during the charging process to the heat dissipating device 100, where the temperature information of the electronic device 300 is used to determine heat dissipation strength or heat dissipation power of the heat dissipating component. It should be appreciated that the electronic device 300 may feed back temperature information to the heat sink 100 in real time, for example, the temperature information may be the temperature of the battery.

Specifically, in actual use, the heat dissipation device 100 may determine the heat dissipation strength or the heat dissipation power of the heat dissipation component according to a preset parameter correspondence based on the temperature of the battery of the electronic device 300 during the charging process. The parameter corresponding relation is used for indicating the corresponding relation between the temperature of the battery and the heat radiation intensity or the heat radiation power of the heat radiation component.

It should be noted that, in one embodiment of the present application, when the charging device is a wired charging device, the wired charging device may output a voltage/current of a pulsating waveform to charge the electronic device. When the wired charging device is connected with the electronic device 300, or the wired charging device is connected with the electronic device 300 through the heat dissipation device 100, the pulsation waveform output by the wired charging device is loaded to the battery, so as to realize charging of the battery.

It should be noted that, the periodic transformation of the voltage/current of the pulsation waveform, compared with the traditional constant voltage and constant current, can reduce the lithium precipitation phenomenon of the lithium battery, improve the service life of the battery, and can also reduce the probability and intensity of arc discharge of the contact of the charging interface, improve the service life of the charging interface, and be favorable for reducing the polarization effect of the battery, improving the charging speed, reducing the heat generation of the battery, and ensuring the safety and reliability during charging. In addition, the charging equipment outputs the voltage with the pulse waveform, so that an electrolytic capacitor is not required to be arranged in the charging equipment, the simplification and the miniaturization of the charging equipment can be realized, and the cost can be greatly reduced.
